The Xbox 360 game console, developed by Microsoft, features a number of first-party and third-party accessories.
Xbox 360 controller
Up to four controllers are able to connect to Xbox 360, including wired and wireless gamepads. The wireless controllers run on either AA batteries (Alkaline or rechargeable) or on a rechargeable battery pack. The wired controllers may be connected to any of the USB ports on the console (the number of ports depends on model: old-style 360s have two at the front and one on the rear, while Xbox 360 S units have two at the front and three at the rear), or to a USB hub. USB keyboards are also supported, but only for inputting text and navigating the dashboard; additionally, the number pad and hotkeys are non-functional. The original first-generation Xbox controllers are not compatible with the Xbox 360. The controller is also compatible with PCs, though wireless controllers will need the Wireless Gaming Receiver. The Xbox 360 controller has been used in the United States and British militaries. The Xbox 360 controller has vibration feedback which is limited to titles using the new XInput API, however, unlike the first Xbox, the face buttons are not analog.
While PS3 and Wii wireless controllers use Bluetooth for connectivity (and can be used with Bluetooth-equipped computers with appropriate software), Xbox 360 wireless accessories communicate over a proprietary 2.4 GHz protocol. In order to accommodate this, Microsoft released the Wireless Gaming Receiver (sold as "Crossfire Wireless Gaming Receiver" in the UK), which allows wireless Xbox 360 accessories to be used on a Windows-based PC. Most Xbox 360 wireless accessories are supported, including standard controllers, racing wheels (without force-feedback), headsets and guitar controllers. The adapter was first revealed at E3 2006 and released on February 16, 2007.
The device acts in a similar manner to an Xbox 360, allowing up to 4 controllers and 4 headsets at a time to be connected to the receiver.
